Eggnog Breakfast Casserole

Eggnog Breakfast Casserole is the perfect stress-free Christmas breakfast to whip up for your family. You have a rich and creamy eggnog casserole that is made with croissants. 

We’re breaking out the eggnog! No other drink reminds of the holidays quite like eggnog. I have to actively remind myself to not drink the whole carton. My kids aren’t though. They used to call it “yellow milk”. Maybe eggnog is an acquired taste? Anyways, I think it tastes delicious!

Eggnog Breakfast Casserole

This year, I made it my mission to do more than just drink our eggnog. I wanted to use it in some recipes and share them with you. Since I’m the queen of breakfast casseroles these past couple months, I figured I’d whip up an Eggnog Breakfast Casserole. I used eggnog in place of the milk/cream. Boy, am I glad I did. This may very well be the best breakfast casserole EVER.

What Type of Bread to Use for this Breakfast Casserole 

For the bread layer, I used croissants. I love the buttery flavor they add to a breakfast casserole. Plus they bake up really nicely in the oven. If you didn’t want to use croissants, you could easily swap for a French bread that is diced up as well or thick Texas-style toast. 

I used a small casserole dish since only my kids are not a fan. I like eggnog in our home. If you use a 9×13 dish, just double the recipe and it should work fine.

We always sprinkle nutmeg on top of our eggnog so I had to make sure it was included. It’s mixed in with the eggs and eggnog.

How Do You Top the Eggnog Casserole

For the topping, I sprinkled on brown sugar and cinnamon. It bakes into a sweet, crispy crust. Beneath that is the creamy eggnog custard and croissants. If you wanted to add maple syrup you can. Fresh berries also work. I thought it tasted fine on its own and it didn’t need any extras.

Consider this recipe for Christmas morning! My kids are not a fan, but I sure enjoy it. Maybe they’ll like eggnog when they are older? You never know. I was a veggie hater till my early 20s.

Other Topping Ideas for Casserole 

  • Fresh fruit
  • Chopped nuts
  • Whipped Cream 
  • A drizzle of maple syrup or honey 

You can honestly top your casserole once it is cooked with almost anything. We tend to eat it with fruit on top or even a sprinkle of nuts for a crunchy texture.

Can I Double this Recipe 

Of course, feel free to make as much of this as you would like. You just want to ensure to use multiple pans if you are making quite a bit, that way it cooks all the way through.

What Type of Croissants to Use in this Breakfast Casserole 

You want to buy the pre-made deli-style croissants for this recipe. Not the Pillsbury dough style croissants. You will find the bakery-style that are pre-cooked are airy, light and soak up all the custard mixture perfectly making this one incredible dish to serve up.

What to Serve with Eggnog Bake 

  • Side of bacon, ham, or sausage
  • Fresh fruit salad
  • Scrambled eggs 

Or whatever else you enjoy eating for breakfast. 

There is no wrong side to pair next to your bake. Or eat it alone if you don’t want to pair it with anything else. I personally love serving it next to some meat. It helps to counteract the sweetness of the casserole. 

How to Store Leftover Eggnog Casserole 

If you have leftovers, make sure to toss them in the fridge and ensure they are covered. Then you can store this casserole in the fridge for 3-5 days. Warm it up in the microwave for a quick reheat, or cover with aluminum foil and heat in the oven. This is even great cold if you don’t want to warm it up. 

Like any casserole, this tends to offer the best texture fresh and warm, but it still tastes pretty fantastic reheated. 

If you are an eggnog fan, I highly recommend grabbing your jug and giving this recipe a try. We love this eggnog breakfast recipe, and will be making it soon once winter begins.
